论文摘要
在这些程序中，我将讨论与夸克gluon等离子体相关的理论的相变的签名。我将以一个说明性的示例，即手性相变，可以通过将极点碰撞作为温度的函数来表征。然后，我将在典型的碰撞中识别弱耦合扇区之间的相互作用，我将引入一个具有弱损坏的对称性的混合模型，该模型具有丰富的准杂化性现象学描述，其中流体动力学和非溶血动力学两极通过共同的分散性关系统一。我将表明能量最初是从软扇区转移到硬部门的，然后在后期不可逆地转移回软扇区，并且该模型再现了许多具有较弱损坏的对称性的耗散系统常见的特征，包括K-GAP。
In these proceedings, I will discuss collisions of poles in the complex plane as a signature of phase transitions for theories relevant to the quark gluon plasma. I will begin with an illustrative example, namely the chiral phase transition, which can be characterized by colliding poles as a function of temperature. Then, recognizing the interplay between weak and strong coupling sectors in a typical collision, I will introduce a hybrid model with a weakly broken symmetry, which has a rich quasi-hydrodynamic phenomenological description where hydrodynamic and non-hydrodynamic poles are unified by a common dispersion relation. I will show that energy is transferred initially from the soft to the hard sector before irreversibly transferring back to the soft sector at late times, and that the model reproduces many features common to dissipative systems with a weakly broken symmetry including the k-gap.
